03 Cell Wall

Join us in this BioSpeak episode as we take a look at the world of the cell wall, a fundamental structure in various organisms. We begin by examining the cell wall's crucial role in protecting and supporting the cell, likening it to a fortress that maintains the cell's shape and integrity. We analyze the unique compositions of cell walls across different life forms: bacteria, archaea, and plants.

Learn about the differences between gram-positive and gram-negative bacteria, the protective elements in archaea, and the polysaccharides that form the primary and secondary cell walls in plants. We also discuss the importance of the middle lamella and plasmodesmata, the tiny tunnels connecting adjacent plant cells that allow for substance exchange.
